翻訳すると二人はデートにいった、と思うのですがニュアンスがわからないです
20年はあと20年かかるってこと?

It might not be exactly what everyone was hoping for, but former long-time coach of Tessa Virtue and Scott Moir, Paul MacIntosh, recent revealed that the two did in fact date
— but a long, long time ago. "The whole world would like them to date. But they were 'dating' at age nine and seven, and I think Scotty broke it off. And he would say that's 19 or 20 years of regret," MacIntosh explained.
